A 60 kg block of ice is being pulled along a well-waxed floor by a rope tied around its center. The rope is taut at an
angle of 55° above the horizontal. If the block accelerates at a rate of 1.8 m/s?, and friction is negligible, determine
normal force necessary to support the block of ice.

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
